Core Rules of Compounds and Ions

These flashcards cover foundational concepts related to ionic compounds, polyatomic ions, naming conventions, and common mistakes in chemical nomenclature.

Ionic Compound

A compound formed from the electrostatic attraction between metals and non-metals, named with the metal first and the non-metal ending in '-ide'.

Polyatomic Ion

An ion composed of two or more atoms that are covalently bonded together, which collectively have a charge.

Roman Numerals

Used in chemical formulas to indicate the oxidation state of transition metals that can have more than one charge.

Balancing Charges

The process of ensuring that the total positive charge equals the total negative charge in a chemical formula.

Sodium Chloride

The chemical compound NaCl, consisting of sodium and chloride ions.

Ammonium Ion

A positively charged polyatomic ion with the formula NH₄⁺.

Iron(III) Oxide

The chemical compound Fe₂O₃, which contains iron ions with a +3 charge.

Common Mistakes in Naming

Examples include forgetting the '-ide' suffix, ignoring brackets, and failing to balance charges.

Sodium Hydrogen Carbonate

The chemical compound NaHCO₃, also known as baking soda.

Calcium Nitrate

The chemical compound Ca(NO₃)₂, which contains calcium ions and nitrate ions.
